Understanding the difference is very important to the overall understanding of electricity and electrical systems, including electric cars and hybrid vehicles. The amount of energy in your batteries (or in your gas tank, for that matter) indicates the distance you can travel before refueling. That's known as range, and it's perhaps the most important issue involved in getting more electric cars on the road. The power rating of your electric motor (or gas engine) tells you how quickly you can turn that energy into useful work, such as vehicle acceleration.
Some utility vehicles are small enough to fit in the back of a full-size pickup truck. Others have different types of tires to accommodate work on turf, rougher terrain, or inside a warehouse. Some run on gasoline, some use diesel fuel and others are powered by electricity. Some have four-wheel- or even six-wheel-drive capability.
While the engine in a conventional vehicle is forced to operate inefficiently in order to satisfy varying power demands of stop-and-go driving, series hybrids perform at their best in such conditions. This is because the gasoline engine in a series hybrid is not coupled to the wheels. This means the engine is no longer subject to the widely varying power demands experienced in stop-and-go driving and can instead operate in a narrow power range at near optimum efficiency. This also eliminates the need for a complicated multi-speed transmission and clutch. Because series drivetrains perform best in stop-and-go driving they are primarly being considered for buses and other urban work vehicles.
